The Randolph-Sheppard Business Enterprise Program provides employment for more than 2,300 entrepreneurs who are legally blind across the United States. Moreover, these entrepreneurs employ an additional 14,000 people, of whom almost 2,000 are visually impaired or have other disabilities (Rehabilitation Services Administration [RSA], 2010). With…

Introduction: In the Province of Quebec, Canada, it is estimated that only about one-third of working-age adults with visual impairments are part of the workforce, despite ongoing efforts of rehabilitation and government agencies to integrate these individuals. The present article describes the development and adaptation of a pre-employment…

Introduction: Development of a sensing device that can provide a sufficient perceptual substrate for persons with visual impairments to orient themselves and travel confidently has been a persistent rehabilitation technology goal, with the user interface posing a significant challenge. In the study presented here, we enlist the advice and ideas of…

Introduction: This exploratory study determined whether transcribing selected test items on an adult life and work skills reading test into braille could maintain the same approximate scale-score range and maintain fitness within the item response theory model as used by the Comprehensive Adult Student Assessment Systems (CASAS) for developing…

This article describes an accessible e-learning environment that was designed to deliver advanced IT skills to legally blind students in preparation for employment. The aim was to convert industry-standard training materials in print into accessible formats and to deliver the learning materials in ways that are more suited to adult students with…

This article describes the application of the Diagnostic Intervention Model and its effects in two case studies of 3-year-old boys, Rolf and Ruud, using individual interaction coaching with their mothers. Positive effects were found for all the target categories in both cases, although an interaction that used materials appeared to be more…

This study evaluated a protocol that was developed to assess how beneficial electronic travel aids are for persons who are visually impaired. Twenty persons with visual impairments used an electronic travel device (Trekker) for six weeks to conform to the protocol, which proved useful in identifying successful users of the device. (Contains 2…

A review of the literature from 1965 to 2008 on tactile maps and models in orientation and mobility yielded four pre-experimental and three experimental articles. The articles were analyzed via best-evidence synthesis--a combined narrative and statistical approach--allowing for recommendations for the most effective use of tactile maps and models.…

A systematic review of the international literature was conducted to investigate the effects and effectiveness of electronic mobility devices. Of the 13 studies that were reviewed, all but one demonstrated effects of the use of these devices, and generally, users evaluated the devices' functionality as beneficial. (Contains 1 table.)

According to the Ministry of Health, Labor, and Welfare of Japan (2006), there are 379,000 persons with visual impairments (both those who are blind and those with low vision) in Japan. Of these persons, 30% travel almost daily, 30% travel two to three days per week, 22% travel two to three days per month, and 11% travel several days a year; in…

This study assessed the efficiency of a model of a familiar urban area for enhancing knowledge of the spatial environment by adults with visual impairments. It found a significant improvement in knowledge of spatial configuration after exposure to the model, suggesting that models are powerful means of developing cognitive mapping in people who…

The capabilities of modern photocopy machines have advanced beyond the simple duplication of documents. In addition to the standard functions of copying, collating, and stapling, such machines can be a part of telecommunication networks and provide printing, scanning, faxing, and e-mailing functions. No longer just copy machines, these devices are…

Macular degeneration is the leading cause of vision loss in the United States for persons aged 60 and older. Compared to individuals without disabilities, individuals with low vision demonstrate a 15% to 30% higher dependence on others to perform activities of daily living. In addition, low vision can adversely affect a person's quality of life.…

Using the expert opinion of more than 30 professionals, this Delphi study set out to develop a set of assistive technology competencies for teachers of students with visual impairments. The result of the study was the development of a highly reliable and valid set of 111 assistive technology competencies. (Contains 2 tables.)

Teachers of students with visual impairments and paraeducators who work with students with visual impairments were surveyed to determine if previous research related to the competencies needed by teachers who supervise paraeducators applied to this subset of special educators. Both groups confirmed the importance of the competencies, but…
